Why would you want to turn off your monitor by keyboard instead of using the the physical monitor button? If you manually turn off the monitor, you can't awaken the monitors with input from the computer. Once you activate the hot key combo and shut down your monitors with PushMonitorOff, any input from the keyboard or mouse will turn them back on.

If you're sporting multiple monitors, clicking two keys on your keyboard also saves you the reach of flipping two, three, or more buttons to power down without feeling like you're shutting down a power station. Don't laugh—when clicking my bank of monitors off, I feel like I should be hearing turbines winding down.

The default combination is SHIFT+F1, but can be modified to any combination you like by accessing PushMonitOff settings via the system tray icon. PushMonitOff is a portable and stand-alone freeware application, Windows only.
